How do I search for forum for previous post??
Do you know the name of the thread? Insert that in the Search bar at the top of the page. Or even the subject of the thread. On the results page, use the filters to select Travel Forum, and newer than 6 months (if the post you are looking for is recent.)
If the post was within the last day or so, you can be specific about the details of that post by replying on this thread, and perhaps someone will recognize it and help you find the thread. Of course this assumes the post or thread hasn't been deleted for some reason.
Do you know who wrote it by any chance? you can look for the user's name and see all his/her posts.
Search is at top left of the page-click on the menu ( 5 white lines) and a Search box opens
Filter by Type and Date
May show up differently on your device
The Search function on the Forum is not helpful at times. If I have enough information about the topic that I want to search, I enter it into Google. The Google function is more refined and will come up with the topic on RSF for me.
